Post differentials. (a). A post differential may be granted on the basis of conditions of environment which differ substantially from conditions of environment in the continental United States and warrant additional pay as a recruitment and retention incentive.
We will also see that in order for a neuron to generate an action potential, the membrane potential has to depolarize from the resting value of around â70 mV to the threshold value of around â50 mV. A similar situation is also at play in muscle cells (skeletal, cardiac, and smooth).
c. Autorhythmic cell starts out at resting membrane potential (~-60 mV), positive out, negative in. d. When the membrane potential gets to -40 millivolts, it has reached threshold for initiating an action potential. e. Potassium channels open, resulting in potassium rapidly leaving the cell. f.
